[jira] [Commented] (CLOUDSTACK-5683) [Automation] - kvm - Live
migration fails with java.lang.NullPointerException. But this is reported
as success.
[ https://issues.apache.org/jira/browse/CLOUDSTACK-5683?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13884029#comment-13884029 ]
manasaveloori commented on CLOUDSTACK-5683:
-------------------------------------------
Observed the same with xen 6.0.2
Steps to reproduce the problem:
Advanced zone set up with 2 xen 6.0.2 hosts.
Deploy few Vms in both hosts.
Live migrate vm from 1 host to another.
